What is the scope and requirements of the wheelchair seating standards (Section 20 of ANSI/RESNA WC/Volume 4 & ISO-16840-4) currently under development?
At the present time, the primary focus of these standards is to provide a means for evaluating the dynamic crashworthiness of after-market wheelchair seating systems independent of testing the seating system on a wide range of commercial wheelchair bases. The primary focus is to develop and validate a surrogate wheelchair base to which the seating system can be attached and dynamically tested on an impact sled in conditions that represent worst-case loading conditions on a range of wheelchair bases. In addition, the committee that is working on the standard wishes to develop a test method that will allow the seating system to be rated with regard to allowing proper placement and fit of vehicle-anchored belt restraints to the wheelchair user. Future efforts on this standard will be directed toward developing design and performance requirements for wheelchair secondary support surfaces, such as head restraints and lateral torso supports, to reduce the likelihood that they will cause inju
